Abstract

PROBLEM TO BE SOLVED: To provide a method which facilitates the pupil of an eyeball to keep still (fix) in a certain direction to save a patient from an anxiety and pain that the patient has during a cataract operation when a doctor indicates the patient "face your eyeball to the left" or "face it to the right", or the patient unstably keeps the eyeball facing in the direction, because the patient is anxious about the eyeball movement causing a failure in the operation.SOLUTION: The method comprises capping the one of paired eyeballs which do not undergo the operation, and using an eyeball directing supporter installed with a means for illuminating a mark to look at a right or left side. The method utilizes a habit between a brain and a nerve to face the paired eyeballs in an identical direction, allowing the operation-free eye to keep on looking at the mark to attain the object of the invention.

Description

The present invention relates to a patient support device for eyeball surgery, and to an eyeball direction fixation support device having a novel structure.

2. Description of the Related Art Conventionally, there have been a great number of proposals regarding a technique related to an instrument that displays an image on a wearing tool such as glasses or conversely projects an image on a retina. There are many ways to give them a lecture while walking, watching TV, watching IT images and recorded images, or reading a lecture manuscript with a glasses-like wearing device without looking at a big monitor screen. It goes without saying here.

As an inventor's actual experience, doctors often indicate the direction of the eyeball during cataract surgery. That is, an instruction is issued to “turn the right eye” or “turn the left eye” during the operation. As a patient, I experienced that it was very difficult. I really felt the need for auxiliary means to make this easier.

The eyeball is naturally pointed toward the object when there is an object, but I realized that it is very difficult when there is no object. It is surprisingly easy to move the eyeball by deciding what to see, but it is very difficult to maintain it when there is no target. In the past, similar techniques could not be found within the scope of patent searches by the present inventors. In addition, I learned that there was no such means in the range that I consulted with an ophthalmologist.

Here, as a new issue, it is a heavy burden on the patient to move the eye to the patient according to the doctor's instructions and point the eye to the left if it is left (to the right if it is right, sometimes up and down). there were. The purpose of the present invention is to make it possible to easily do so without imposing a heavy burden on the patient. It is said that there are rarely people who can move the left and right eyeballs independently. Such people are not targeted. The present invention does not target a specific person, but targets a general eye patient.

In such a case, when it is difficult to know that if the surgery fails, the patient's psychological anxiety and fear / tension are immeasurable burdens / pressures. The object of the present invention is to alleviate these burdens as much as possible, and to provide new auxiliary means.

Based on his own experience, the present inventor has studied for a long time, utilizing surprisingly important knowledge, and using that knowledge, he helps the doctor with cataract surgery (reduces the probability of failure) Found that the major psychological burden could be reduced. One of the main points is that attention is paid to the eyeball that is not the target of surgery, and the general person tends to point the left and right eyeballs simultaneously in the same direction. In the case of left eye surgery, the invention is directed to the right eye. Hereinafter, since the opposite expression is the same for the left and right, it will not be described in detail below.

(1) The essence of the first invention is an eyeball direction indicator for surgery, in which a structure part that covers the reverse eyeball to be operated and a light guide is turned on or light leakage (transmission) It is a patient's eye direction support device that easily fixes the direction of the eyeball to be operated, which is configured to take any configuration that generates guide light.

(2) The gist of the second invention is the gland 1 according to the gist 1, wherein the light guide comprises a light source unit by turning on an LED on a structure part covering the reverse eyeball of the surgical object. It is a patient's eye direction support device that can be easily fixed.

(3) The outline of the third invention is the above-described outline 1, in which the structure part covering the reverse eyeball to be operated and a small hole for generating guide light as leakage of light from the covering fabric for operation are provided. It is a patient's eye direction assistance device that easily fixes the direction of the eye to be operated, which is characterized by having a configuration.

(4) The gist of the fourth invention is the above-described gist 1 in which a plurality of small holes in which guide light is generated as leakage of light from the structural part covering the reverse eyeball to be operated and the farac for covering for operation. This is an eye direction support device for a patient that easily fixes the direction of the eye to be operated, characterized in that it has a structure in which holes other than those required by a slider are further closed. .

(5) The gist of the fifth invention is an eye direction indicator for surgery, and is a surgical object characterized in that an image for guiding the eye direction can be projected onto a structure part covering the eyeball opposite to the surgical object. It is a patient's eye direction support device that easily fixes the eye direction.

(6) In the sixth aspect of the present invention, the structure that covers the reverse eyeball to be operated and the light guide is turned on, or the guide light is generated as a light leak, or is projected as an image. In addition, a surgical object characterized by a structure in which an object that is too close to the eyes is also combined with a structure that is provided with a correction lens so that the focus is at a distance that is easy to see. It is a patient's eye direction support device that easily fixes the eye direction.

(7) The gist of the seventh aspect of the present invention is that the guide eye or the position control of the image to be projected is performed manually or by voice in the above-mentioned skeletons 1, 3, 5 easily. It is a patient's eyeball direction support machine to be fixed to.

FIG. 1 is a diagram for explaining the knowledge underlying the present invention. Now, let us assume that the left eye requires surgery. At this time, the work of the present invention is performed around the right eye. (Hereafter, when the right eye requires surgery, it is possible to omit the duplicated explanation by replacing “left” and “right” respectively)

The doctor says that the eyeball to be operated is “to the left”, “to the right”, “to the top”, or “to the bottom”. At this time, the object (picture or light) is given to the eyeball that is not the subject of surgery, and fortunately when the right eye sees it, the eyeball (left eye) of the subject will see its direction, that is, the same at the same time. It moves in the direction (general people move to make the distance between the left and right pupils constant in order to measure the distance to the object).

FIG. 1 is an explanatory diagram assuming that the face is cut from the top at the eye position. 1 is a left eye, 2 is a nose, 3 is a right eye, 4 is a pupil, 5 is eyelashes, and 8 is a light source or object. Both the left eye and the right eye are looking at the light source R1. This means that when a pupil cannot move the pupil to the right or when the visual field is constricted, the center can be sequentially shifted to R2, R3, and R4. When normal, R1 alone is sufficient. These can be confirmed by prior inspection.
When the right eye sees the object R1 (light source or picture), the left eye also sees the direction at the same time, that is, moves in that direction.

It is an invention that utilizes the knowledge that a pair of eyes can be moved and a patient can easily move an eyeball to be operated without anxiety as instructed by a doctor. Since the range that can be moved differs depending on the person, it is possible to confirm by moving to R2, R3, R4 in advance (most) to the right or (most) to the left. R1 is the rightmost, but when it becomes R2, R3, R4 in sequence, the eyes approach the center direction. (R means right, right, L means left, left)

Assuming the case of the reverse eye, L1, L2, L3, and L4 are drawn in FIG. 1, but the description is omitted because it is exactly the same as the right eye. With regard to the movement of the eyes, it was confirmed that the pupil of the left eye was pointing in the R1 direction when R1 was viewed with the right eye while holding the palm over the C1 position so that R1 was not visible to the left eye. Hands are sufficient, but you can stand under the nose 2 because anything like underlays or cardboard is acceptable. The broken line of C1 means these. (C means center)

FIG. 2 is a diagram for explaining a cap for covering eyes and exposure. When the left eye is an eyeball to be operated, a cap 6 is put on the right eye, and the black eye 6 is made of a material that does not allow light to pass therethrough, and there are a plurality of exposure holes 8 (8-1, 8-2). 8-3) This shows a certain state. A state in which there are a plurality of exposure holes 9 (9-1, 9-2, 9-3) for viewing the left is shown. Although not shown here, if the slider 10 provided in the central depression of the small cover is moved and now light leaks through only the hole 8 (right direction), the right eye sees the direction, but the left eye Is also moving to the right.

FIG. 3 shows an example of the eyeball cover 6, in which the upper direction is the eyebrows (upward or head direction), the left is the facial skin direction, and the lower is the jaw (chin, ie downward direction). Cover your eyes with this. 3 in FIG. 3 corresponds to the hole 8-1 in FIG. 2 and 3 are different in the viewing direction. 3 is a groove for the slider (10), in which the slider 10 is fitted, and a plurality of holes 12, 13, and 14 are provided in the groove for the slider. Light passes only when the hole 12 and the hole 12 provided in the groove coincide. This eyeball cover exposes only 14 copies, so the eyes see it. The left eye is directed toward the head of the eye, that is, toward the nose.

The eye cover is not limited to materials such as hard plastic, soft plastic, metal such as silicone rubber, urethane rubber, and stainless steel, glass, and ceramics. Even if the cover is not perfect, it can be in the form of glasses or goggles if it can be specified only in the viewing direction, and it can be exposed. Since it is used for medical purposes, it should be capable of chemical sterilization / sterilization, hot water sterilization / sterilization, gas sterilization / sterilization, radiation sterilization / sterilization, and the like. For fixing to the eyes, you can use a bandage. The surgical fabric is covered from above. Since the shape of the face (the shape around the eyes) varies, a common divisor shape is prepared. In addition, in order to avoid hepatitis, AIDS, cancer, etc., the unemployed cloth after surgery is usually immediately enclosed and incinerated after surgery.

As the light source, transmitted light (exposure) passing through a surgical fabric is used. For stability, an LED (light emitting diode) light source, which has recently made remarkable progress in performance and downsizing, is preferably used. In this case, a power source and a battery are required. Small or solar cells may be used, and afterglow and phosphorescent tape are also effective. Since it is not a long-time operation, it should be suitable for sterilization and sterilization. Some people have shown that a small hole can be made in a cup.

After knowing the present invention, various operations such as various applications and applications are possible. In the case of LED, it is preferable not to be too dazzled. In addition, blinking and coloring that make it easy to know the direction of the pupil is also preferable. Smaller drawings and drawings are also acceptable. The hole of light may be penetrating or not. The electronic board for LED is preferably a fitting type or a sealed type. Further, it may be a non-passing type in which a transmissive material is fitted, such as stained glass.

It is normal for the object to be bound to the direction of light. This is because it is rare to see a focal point of about 1 to 3 centimeters from the eyes. Therefore, it is extremely preferable to attach a lens so that the light source (including transmitted light and pictures and drawings) is in focus. For the eyes, if the lens is corrected so that it is in focus at a distance of about 30 cm, the patient is more focused than the blurred object. It is easy to perform surgery. Such lens attachment is preferred and is included in the claims.

The surgeon is performing surgery using both hands. For this reason, it is very difficult to indicate the direction of the eyeball by operating a joystick or the like. To reduce this operation, it recognizes the voice produced by the doctor, whether it is pointing right or down, and guiding it. I came to the conclusion that it was best to control the light. Further, during the operation, for example, in the case of cataract surgery, disturbance noise such as noise at the time of pulverization of the crystalline lens or suction sound of the pulverized crystalline lens is generated. In order to solve this problem, by adopting a bone mission microphone as a microphone, it is possible to collect only the utterance sound of a doctor without picking up a disturbance sound.

1) According to the present invention, it is possible to easily fix the patient's eye to be operated in the designated direction.
2) The patient's psychological burden and mental burden could be reduced.
3) Since the goal has been decided, the movement of the eyes has been stabilized, so the probability of surgical failure can be reduced. This also increases the level of security for doctors.
4) Since it covers other eyes, it also protects other eyes for surgery.

5) It is possible to see the movement of the eye to the left and right and to fix it by seeing the object that is clear by inserting the lens, instead of the object that is crisp.
6) Because it is an eye not related to surgery, it can be used with confidence.

These are the figures for confirming and explaining the linkage of the left eye and the right eye, which is the basis of the present invention. FIG. 3 is a diagram for explaining a cap for covering eyes and exposure. Shows an example of an eyeball cover, and shows an example of a cap whose light spot (viewing direction) can be changed by moving a slider. These are the figures which attached the lens for focusing on a target object. These are the figures for demonstrating position control manually and lighting control of a guide light. These are views in which display position control is controlled by voice recognition, and video display is displayed on a liquid crystal panel.

In the present invention, the “eye cap” is provided to protect the eyes. It is preferable to incorporate an LED light-emitting part. In particular, when the light-emitting part is used while being overlapped with a cap, the person in contact with the eyes is separated and easily sterilized with a chemical solution, and blinking is also easy. In addition, it is difficult to focus immediately before the eyes, but if it is corrected with a “correction lens” at an appropriate distance, it is easy to direct the trend in that direction. A glass or stainless steel cap that is easy to sterilize and a simple structure with only two holes (on the side of the eye and on the outside of the eye) are preferred. This is because it is possible to practice in advance.

In principle, the present invention can be broadly classified into (1) exposure type, (2) LED type, (3) afterglow type, and (4) video projection type. (1) The exposure method can be the light that has passed through the covering at the time of surgery, (2) the LED method is a method that determines the viewing direction with the help of electricity, and (3) the afterglow method is the physicality of phosphorescence.・ It is a method that shines with chemical help. (4) The image projection method is a method for displaying an image on a liquid crystal panel (the image is for guiding the eyeball direction and is called a guide image). Although the term “LED” is used here, it is a term representative of a thing that shines, and may be a micro light bulb.

The following examples illustrate the invention in more detail. However, this example does not limit the effectiveness of the present invention. Rather, it will bring about further development.

(Movement of the eyeball that is the basis of the invention: part 1)
Ask the collaborators to put their palms towards the nose (the index finger on the right hand touches the base of the nose, and the position of the dotted line C1 in FIG. 1). Blocked it so that it could not be seen. I looked at the target point light source on the side of my eyes. The pupil of the right eye turned to the right. At that time, the direction of the pupil of the left eye was directed to the right even though the target point light source was not visible. From this, it was confirmed that the left eye moved in conjunction with the right eye.

(Movement of the eyeball that is the basis of the invention: Part 2)
Next, when the left and right eye positions were changed and confirmed, the same linkage was confirmed. At that time, the cardboard was placed on the nose and observed.

(Eyeball movements as the basis of the invention: Part 3)
Next, we asked more people (old and young) to confirm. At that time, the cardboard was placed on the nose and observed.

Next, the ping-pong ball was half cut, painted black with magic ink, and applied to the eyes. The part that does not follow the skin was cut appropriately. A small hole was made near the corner of the eye. When looking at that direction with the right eye, the left eye was also pointing to the right (in the direction of the nose). The face was covered with a disposable fabric (polyester-pulp composite: non-woven fabric widely used in the world: water-repellent “Sontara”: trade name) in the same manner as surgery. The light spot was sufficiently visible with the transmitted light. However, in consideration of the light condition at the time of surgery, it has been found that it is also a good means to shine with an LED. The test is shown in Example 3.

The LED was affixed to a glass beetle, and the other portions were painted black and covered with the right eye. When the LED on the outer corner of the eye is illuminated and viewed, the left eye is facing the eye, and when the eye is illuminated and viewed with the right eye, the pupil of the left eye is directed toward the outer corner of the eye. It was. It has been found that the material is preferably deformed stainless steel. (It is hard to break, it does not rust, it is easy to heat and sterilize, and it is often used as a material for surgical tools.)

In FIG. 5, a joystick 19 (joystick is one of the input devices used in game machines and the like for manually determining the position of guide light (light for guiding the eyeball direction) and guide video. It is a kind of “pointing device” that specifies the input position and coordinates.It is input by tilting the lever back and forth, left and right, or pressing a button. An A / D conversion unit 20 is provided to digitally convert the position change amount from the joystick, and a position displacement detection unit 21 is provided to determine the position change amount from the change amount. In order to determine the guide light to be lit from this position displacement, the lighting position is determined by the guide light lighting position calculation unit 22. It was found that the pupil of the subject moved in the same direction according to the amount of change in the joystick as the guide light changed by moving the joystick back and forth and left and right.

This is an embodiment for positioning display of guide light and guide video according to the voice of the surgeon. Microphone 28 (preferably a bone oscillating microphone: to avoid the influence of external sound during surgery), wireless transmission unit 29 (transmits sound), wireless reception unit 30, and A / D conversion unit for digitizing the audio signal 31. An FFT calculation unit 33 is provided to convert the input data to the voice recognition unit, and frequency analysis is performed to obtain a power spectrum value and a peak frequency, which are input to the voice recognition unit 35. The speech recognition engine is a well-known neural network. Based on the recognition result, the video position calculation unit 36 calculates the video display position. The calculation result was output to the liquid crystal display driver 37. Guide images (guide lights) are displayed on the right, left, upper, and lower sides of the liquid crystal display panel according to the right, left, upper, and lower utterances, and the pupils of both eyes of the subject move in the same direction according to this display. I found out. A number of means for the FFT and neural network employed in this embodiment are well known, not to mention here.

Specifically, the present invention is not a medical device, but is an auxiliary device at the time of medical care, and reduces the painful position of the patient. At the same time, it helps doctors who are in trouble if they move during surgery. As a specific development example, it helps surgery such as cataracts. Certainly, there has been a history of the operation so far without the present invention, but these eye operations are indirectly (psychologically) and partly direct to both patients and doctors.
